Wrong recorded power affects my critical power curve

My trainer / Zwift has recorded the wrong power one time since I started Zwifting in 2017. I don’t know when. This affects my critical power curve. The curve shows that I’ve had 2000 watts for a few seconds before it goes down to a normal curve.

I would like to find and delete the Zwift activity that contains the wrong reading, so that my power curve on Zwift is more correct.

Any tips to how I can find and delete the activity with max wattage of 2000 watts?

Thanks!

Ps: I am able to use the power curve on Strava (and on Garmin Connect), but it seems that these two integrations have discarded the high reading. I am not able to find it by sorting on max wattage here.

If this is a PC (or Mac I think) the file should be located in \documents\zwift\cp

Just delete the file with the date that the abnormal wattage occurred.

Will Zwift assemble the power curve only from the files on the computer?

… in that case there will be different power curves if I use different computers?

Yes and Yes.

should not a rider’s power curve be part of their profile and the same on whichever platform the game is played?

Yes, should be.
